Thank you Jugal and good morning everyone. During my comments I will reference the slides posted on our website last night starting on Slide 9. In the first quarter value added sales, which exclude the impact of pass through precious metal costs were $257.8 million down 14% from prior year. Despite strength in aerospace and defense and consumer electronics our sales were negatively impacted by declines in semiconductor and automotive plus the expected inventory correction for our nonresidential construction material.
Additionally, as Jugal commented, some temporary operational challenges limited our shipments, particularly in Performance Materials. Our teams have made meaningful progress in mitigating these challenges and expect more normal levels of output in the second quarter. When looking at earnings per share, we delivered adjusted earnings of $0.96 in the first quarter down 28% from prior year.
Moving to Slide 10. Adjusted EBITDA in the quarter was $45.2 million, 17.5% of value added sales, down 15% from the prior year with roughly flat margins. Despite the significant sales decline, the strong margin performance was driven by positive price and the benefit of our cost improvement initiatives partially offsetting the volume decline.
Moving to Slide 11. Let me now review first quarter performance by business segment. Starting with Performance Materials. Value-added sales were $155.6 million, down 7% from prior year. This year-over-year sales drop was driven by lower demand in automotive, commercial aerospace and the nonresidential construction application within industrial. Space and defense remains a bright spot with significant contribution from the emerging space market and strong defense demand more than offsetting declines in commercial aerospace.
EBITDA, excluding special items, was $35.7 million or 22.9% of value-added sales, down 17% from the prior year period. This decrease was driven by the lower volume, partially offset by targeted cost improvement initiatives.
Moving to the outlook. We expect space and defense to remain strong throughout the balance of 2024 and again, expect the operational challenges to improve as we move into the second quarter.
Next, turning to Electronic Materials on Slide 12. Value-added sales were $77.6 million, down 25% compared to the prior year as a result of continued weakness in the semiconductor market. EBITDA, excluding special items, was $14.5 million or 18.7% of value-added sales in the quarter. Despite significantly lower volume, operational performance and cost improvement initiatives helped mitigate the semiconductor slowdown, which drove approximately 500 basis points of margin expansion year-on-year.
As we look out to the rest of the year, we expect a gradual semiconductor recovery from Q1 with sequential improvement as we move through the balance of the year.
Finally, turning to Precision Optics segment on Slide 13. Value-added sales were $24.6 million, down 8% compared to the prior year. This year-on-year decrease was mainly driven by reduced demand in industrial and automotive, partially offset by strength in space and defense. Precision Optics also saw some operational challenges, which delayed some shipments out of Q1. EBITDA, excluding special items, was $0.4 million or 1.8% of value-added sales. The decrease in volume was a significant driver of this year-over-year decline in addition to unfavorable product mix. Looking out over the next few quarters, we expect a meaningful step-up in margin performance in Q2 with stronger demand and continued focus on cost improvement initiatives.
Moving now to cash, debt and liquidity on Slide 14. We ended the quarter with a net debt position of approximately $462 million and approximately $130 million of available capacity on the company's existing credit facility. Our leverage at 2.2x remains just slightly below the midpoint of our target range.
Lastly, let me transition to Slide 15 and address the full year outlook. Despite the slow start to the year, we expect to deliver another year of record results with our organic and operational initiatives more than offsetting some market softness. Since our initial guide for 2024, the outlook for commercial aerospace and electric vehicles have softened. And as Jugal mentioned, we are expecting some inventory correction from our Precision Clad Strip customer in the back half of the year. We also expect slightly higher interest expense based on the current rate outlook. While we will work to mitigate much of these headwinds, we are adjusting our full-year guide to a wider range of $5.60 to $6.20 adjusted earnings per share, a 5% increase from the midpoint versus the prior year.
Despite the mixed market environment, Materion remains poised to deliver another year of strong execution and record results in 2024.
This concludes our prepared remarks. We will now open the line for questions.
